Yes, you could do that but you would also have to deal with bronzing 
problems.  Eboni alone +PremierArt PrintShield on semigloss or other RC 
papers will not bronze.  The other non-bronzing alternative that I'm 
now using for RC papers with QTR is no black ink at all.  This way I 
don't have to bother with spraying.  "Plain Jane" Epson Photo Paper 
gives the best performance with the latter technique.
